quickstart: check if domain was registered recently, and warn about potential deliverability issues ...

we use 6 weeks as the cutoff, but this is fuzzy, and will vary by mail
server/service provider.

we check the domain age using RDAP, the replacement for whois. it is a
relatively simple protocol, with HTTP/JSON requests. we fetch the
"registration"-related events to look for a date of registration.
RDAP is not available for all country-level TLDs, but is for most (all?) ICANN
global top level domains. some random cctlds i noticed without rdap: .sh, .au,
.io.

the rdap implementation is very basic, only parsing the fields we need. we
don't yet cache the dns registry bootstrap file from iana. we should once we
use this functionality from the web interface, with more calls.
